How To Draught Proof Windows

Draughts can be an ongoing issue in homes, especially during colder months.

These unwanted currents of cold air not only make rooms feel chilly and uncomfortable, but also contribute to increased energy bills as heating systems work harder to maintain a consistent temperature.

Draught-proofing windows is a simple, yet effective solution to increase both comfort and energy efficiency within your home.

Why draught proofing matters

Draught-proofing your home is more than just keeping cold air out: it’s a vital step towards creating a more comfortable living environment.

Properly sealed windows and doors help your home retain warmth better, leading to less reliance on heating systems.

Uncontrolled draughts significantly impact heating costs. As warm air escapes, your heating system has to work harder to maintain a consistent indoor temperature.

Reducing draughts and limiting heat loss will lower the energy required to heat your home, saving you money.

Sources of draughts from windows

There are some common sources of draughts to be aware of in properties:

Gaps around the window frame: Small gaps can develop around the window frame due to shifting or settling in the structure over time. These gaps allow cold air to seep in, making maintaining a consistent indoor temperature harder.

Worn or damaged seals: Window seals play a critical role in preventing draughts. However, with age, these seals can deteriorate, leading to increased airflow and energy loss.
Faulty or ageing window frames: Older windows, particularly those made from wood, are more susceptible to draughts. With time, materials can warp, crack, or shrink, creating small openings where air can enter.

How to stop draughts from windows

Stopping draughts from windows involves identifying and addressing the most common sources of air leakage.

Check & seal gaps

To check for gaps around window frames, hold a lit candle or a smoke pen near the edges of the window on a windy day.

If the flame flickers or the smoke wavers, there’s likely an air leak. Once you’ve identified these gaps, seal them with caulk or weatherstripping to create an airtight seal.

Caulking works well for non-moving parts of the window frame, while weatherstripping is ideal for areas where the window may still need to open and close.

Add or replace window seals

Window seals are crucial for keeping draughts out, yet they can degrade over time. Replacing or adding window seals can improve insulation and reduce energy costs. There are several types to consider:

Rubber seals are durable and suitable for areas prone to moisture.
Foam seals are cost-effective and easy to install, but may not last as long.
Silicone seals offer flexibility and long-lasting performance.

Draught excluders

Draught excluders are simple but highly effective devices that block unwanted air from seeping through gaps around windows.

Typically made from materials like rubber or foam, they come in the form of brush strips, adhesive strips, or rubber flaps, and are installed along window edges where air tends to leak.

Installing draught excluders not only stops cold air from entering, but also keeps warm air inside.

Use thermal curtains or blinds

Multi-layered curtains or honeycomb blinds create an insulating barrier, helping to maintain room temperature.

Use low-E coating or film

Low-emissivity coatings reflect interior heat back into the room, reducing energy loss. This can be applied to the glass or installed as part of a window replacement.

FAQs on draught proofing your home

What maintenance is required after draught-proofing windows?

Regularly check your window seals for any signs of wear or peeling, especially after extreme weather. Cleaning the window frames and seals periodically can prevent dust and debris from compromising the seal’s effectiveness. Reapply or replace the draught-proofing materials as needed to maintain performance.

Does draught proofing have any impact on noise reduction?

Yes, sealing draughts can also reduce noise levels from outside. By closing gaps around your windows, you can limit the amount of external noise that enters your home, creating a quieter indoor environment, particularly in busy areas.

Will draught proofing my home increase property value?

Effective draught proofing can make your home more energy-efficient and comfortable, which may appeal to potential buyers. Energy-efficient homes are often seen as more attractive on the market, as they offer reduced running costs and improved environmental impact.
